When we first learn how to write regular expressions, we're happy if we can find a pattern (any pattern!) which seems to match the input data. Efficiency isn't high on our minds, after all "everyone knows that regular expressions are slow!".
This talk will attempt to provide a greater understanding of how regular expressions work. Particular emphasis will be placed on greediness and its impacts on efficiency. A handy regular expressions tool, called the Regex Coach (which is free-as-in-beer) will be used to help show-case the examples.
Some mention of corollary Perl myths may be made, but in general the paper will be largely open for developers of any language.
Life is an adventure, and I'm tackling every challenge I can. I run a business, travel continuously and love deeply.
